#机器学习及数据挖掘

在做实习推荐算法工程师时学习到的一些算法将会贴在这里

###增强学习

  1. UCB(upper confidence bound)上置信度算法
  2. 抓取商品的URL

###文件列表

  1. UCB算法:

    1. 最初的C++编写的UCB1算法基础类
    2. 使用基于C++11和boost1.56编写,名为served的http服务器,开发的UCB算法测试demo。
    3. C++UCB类的json解析速度测试
    4. 重新使用python编写的UCB类,使用Python的tornado异步非阻塞的web服务器搭建的UCB推荐服务器
  2. 抓取商品URL:

    1. 抓取什么值得买的双十一购物清单的商品URL,使用shell与python混编。
  3. 分析用户操作记录,给用户关注的店铺,品牌,列表排序:

    1. 用户对商品的操作记录有:点击,购买,收藏,拉黑
    2. 通过MySQL数据库得到商品对应的品牌,店铺,或者列表,记录下每个店铺的操作记录
    3. 通过打分,将用户的关注店铺,品牌排序,将结果保存在redis数据库中
